> As you can imagine i have installed fully RH 7.1 and wanted to
configure sendmail to act as full email server, which means SMTP and
Pop3 server altogether in the same machine (if that is possible)
Sendmail is already installed there, but it seems to work only for the
local machine. I do not want to compile again the whole sendmail.cf file
since it is a huge work . Is there any place where i can find some
information just how to modify sendmail.cf file in order to accomplish
what i need (or at least to find a sendmail.mc file).

My recommendation would be to uninstall Sendmail, and install something
easier to use, faster, newer, and well-supported, such as Exim.  Just my
personal preference.

RedHat has an rpm for the older 3.x series of Exim.  There are also a
number of people who have built rpm's for the new 4.x series.  I do
recommend the 4.x series, because it is even easier and more flexible to
use.  See www.exim.org for more details.  But DO NOT try to run both
Sendmail and Exim on the same machine.  (There is no need to do so,
anyway.)

As far as I know, neither Sendmail nor Exim handles POP3, because they
are SMTP servers, not POP servers.  But RedHat provides a decent POP3
service.  (Take a peak at /etc/xinetd.d and see if there's anything like
ipop3d in there.  If so, just enable it.  "cat" the file (it is small)
and it should be obvious what edit is required.  Then restart xinetd.)
Yes, you can absolutely run both servers on the same machine.  In fact,
I think it would be easiest to do so; otherwise you'd have to configure
one or the other to push or pull emails between the two machines.
